|
|
|
|
<p>Backbone connector for a CouchDB backend.</p>
|
|
|
|
<p>Usage:</p>
|
|
|
|
<p>var backend = new recline.Backend.CouchDB();
|
|
var dataset = new recline.Model.Dataset({
|
|
db<em>url: '/couchdb/mydb',
|
|
view</em>url: '/couchdb/mydb/<em>design/design1/</em>views/view1',
|
|
query<em>options: {
|
|
'key': 'some</em>document_key'
|
|
}
|
|
});
|
|
backend.fetch(dataset.toJSON());
|
|
backend.query(query, dataset.toJSON()).done(function () { ... });</p>
|
|
|
|
<p>Alternatively:
|
|
var dataset = new recline.Model.Dataset({ ... }, 'couchdb');
|
|
dataset.fetch();
|
|
var results = dataset.query(query_obj);</p>
|
|
|
|
<p>Additionally, the Dataset instance may define three methods:
|
|
function record<em>update (record, document) { ... }
|
|
function record</em>delete (record, document) { ... }
|
|
function record<em>create (record, document) { ... }
|
|
Where <code>record</code> is the JSON representation of the Record/Document instance
|
|
and <code>document</code> is the JSON document stored in couchdb.
|
|
When _all</em>docs view is used (default), a record is the same as a document
|
|
so these methods need not be defined.
|
|
They are most useful when using a custom view that performs a map-reduce
|
|
operation on each document to yield a record. Hence, when the record is
|
|
created, updated or deleted, an inverse operation must be performed on the original
|
|
document.</p>
|
|
|
|
<p>@param {string} url of couchdb database.
|
|
@param {string} (optional) url of couchdb view. default:<code>db_url</code>/<em>all</em>docs
